Background:Infantile tremor syndrome (ITS) is characterized by anemia, skin pigmentation, tremors, physical, and mental regression without a defined etiopathogenesis and low incidence.Materials and Methods:We have studied 9 patients over 1 year for the changing clinical and laboratory variables of patients with ITS. Neuroregression and anemia were presented in all followed by tremors in 5 and hypotonia in 2.Result:Sepsis screen was positive in 6 and urine cultures in 2. Antibiotics were required in 6. ITS with changing parameters still significantly contributes to healthcare burden.Conclusion:It is important to screen for urinary infection and septicemia to avoid antibiotic abuse.
